Abstract (en)

[origin: EP0056717A2] An improved method of and apparatus for magnetically filtering a magnetically susceptible component in a fluid (F) with a matrix (5) of magnetizable material which, when magnetized, provides a multiplicity of regions of high magnetic field gradient. A sequence of time-spaced impulsive magnetic fluxes is produced in an electromagnetic coil (24) by periodically charging and discharging a capacitor (13) connected to the coil (24), said fluxes being concentrated across the magnetic matrix (5) to magnetically entrap the magnetically susceptible component in the regions of high field gradient therein. A static magnetic flux may also be provided in said matrix (5) by permanent magnet means (22,23) included in a magnetic circuit with said matrix (5).
